rescue missions, and being prepared
it took a bad crash back 25 miles in bad weather last year, when a buddy shattered his hip to realize that i did not prepare myself properly for an emergency. Cutting numerous branches and laying them on the snow helps to retain body heat, also buy new heat packs every year, 8 out of every 10 packs that my riding buddies were carrying in there sled were old and didn't work. also aspirin and lots of it come in handy, 3 0r 4 tablets are not enough. raisins and peanuts are excellent for retaining body heat and energy when you are cutting branches for shelter.
